Identification of three quantitative trait loci associated with partial resistance to P. sojae in the OX20-8 × PI 398841 population using the genome-wide LOD threshold

Chr.a	Position (cM)b	Nearest marker	LODc	R 2 (%)d	Additive effect (contributor)e
1	71	BARC-044479-08708	4.4	4.6	−1.26 (PI 398841)
13	51	BARCSOYSSR_13_1103	14.8	16.1	−2.12 (PI 398841)
18	91	BARC-031343-07057	3.4	3.6	−1.02 (PI 398841)

^aChromosome numbers

^bPosition (cM) on Consensus Map 4.0 (Hyten et al. 2010). Since BARCSOYSSR_13_1103 was not integrated on the Consensus Map 4.0, an approximate position was denoted based on the adjacent marker, Satt334, on the Williams82 genome assembly Glyma1.01

^cA genome-wide LOD threshold was 3.1 at 95 % of confidence level by a 1,000-permutation test

^dPhenotypic variance explained by the QTL

^eThe negative additive effects indicate that PI 398841 contributes favorable alleles for the QTL
